Outline of Final Research Achievements

We developed 3 different charge-transfer complex films (CT films) consisted of electron-acceptor unit and electron-donor unit and clarified the relationship between molecular structure and function of CT films. 3 different CT films are formed by 1) different donor molecules/single acceptor polymer, 2) single donor molecule/different acceptor polymers and 3) donor polymers/acceptor polymers. Study of type 1 and 2 suggested that the small molecules which did not have large functional groups near donor or acceptor unit could form CT complex in the solid films. From type 3, we could firstly confirm that acceptor polymer and donor polymer could form CT complex in the polymer blend.
From these research, we clarified that several properties of CT films could be easily controlled by changing acceptor/donor ratio. Therefore, CT film method would be a useful and versatile process to make new polymeric materials.
